RAIL-JOINT.

To all whom it may concern: Y

Be it known that I, REIMER N. DITHMER, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and Stateoflllinois, have invented certain new and useful improvements inRail-Joints, of which the following is a specification.

My invention relates to improvements in rail joints and has for itsobject theprovision of an improved joint of this character which is ofsimple construction and eiicient in operation.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which- Y Figure lis a side view illustrating the ends of two-rail sections embodying myinvention and shown in assembling positions, Fig. 2, a side elevation ofthe jointv shown assembled, Fig. 3, a perspective view of the end of oneof the rail sections, and Fig. 4i, a perspective view of the end of theother rail section.

The preferred form of construction as illustrated in the drawingcomprises ordinary rail sect-ions l and 2 having the usual The ends ofthe heads and the lower portion of rail section l is extended to form asupporting projection 3 and the upper portion of the other rail section2 is extended at i to rest upon projection 3 and form a smoothcontinuation of the head of rail section l as indicated. Rail section lis provided with side projections 6 at each side of the upper portion ofthe end thereof and adapted to embrace the projection 4; and a portionof the web on the rail section 2 when the parts are assembled and restand ride upon side projections 7 projecting from the lower portion ofthe web of the rail section 2. The under sides of the projections 6adjacent rail section l are upwardly recessed at 8 to permit the rockingof the ends of the projections 7 therein for assembling or disconnectingthe joint and the outer under sides of the projec tions 6 are iiattenedat 9 to ride and slide upon the top portions of projection 7 to permitmovements due to temperature expansions and contractions. Thisarrangement constitutes a simple and effective joint for Specificationof Letters Patent.

`ing from the spirit of the invention.

therefore, do not wish to be limited to thev Patented ret. 3,1914.

Application mea august 2, 1913. serial No. 782,609.

the purpose in which the parts are so interlo'cked as to constitute asmooth joint when a wheel approaches from either direction and alsopermits of temperature expansions and contractions.

Each of the rail sections l and 2 is provided with a recess l0 o-n eachside adjacent the joint, said recesses being adapted to receive the noseor head of a spike and serve as the means for securing the rail joint tothe ties of the road bed.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departprecise details of constructionset forth, but desire to avail myself of such variations andmodifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

l. A rail joint comprising two rail sections, one of said sectionshaving the lower portion of its web projected to form a supportingprojection .and the other section having its head and the upper portionof its web projected to rest upon the projection on the other section;and side projections on each of said rail sections embracing the webprojection of the other, substantially as described.

2. A rail joint comprising two rail sections, one of said sectionshaving the lower portion of its web projected to form a supportingprojection and the other section having its head and the upper portionof its web projected to rest upon the projection on the other section;and side projections on each of said rail sections embracing the webprojection o-f the other, the upper side projections being recessed ontheir under sides adjacent the corresponding rail section and havingtheir outer under sides flattened and sliding upon the top surfaces ofthe side projections of the other section, substantially as described.

3. A rail joint comprising two rail sections, one of said sectionshaving the lower portion of its web projected to form a supportingprojection and the other section having its head and the upper portionof its web projected to rest upon the projection on the other section;and integral side projections on each of said sections embracing the webprojection of the other, each of said rail sections being inwardlyrecessed on each side adjacent the joint to receive the nose of aretaining spike, substantially as described.

4. A. rail joint comprising two rail sections, one of said sectionshaving the lower portion of its web projected to form a supportingprojection and the other section having its head and the upper portionof its web projected to rest upon the projection on'the other section;and integral side projections on each of said sections embracing the webprojection on the other, each of said rail sections being inwardlyrecessed on each side adjacent the joint to receive the nose of aretaining spike, and the upper side projections being recessed on theirunder sides adjacent the corresponding rail section and having theirouter under sides flattened and sliding upon the top surfaces of theside projections on the other railsection, substan tially as described.l

In testimony whereof I have signed myY name to this specification in thepresence of two subscribing witnesses.
